Error HTTP/2 stream 0 was not closed cleanly:

Support Installation and Deployment

Hello all,

I setup tyk successfully with loadbalancing with Consul. But from one of the API microservice I get the below error when used with CURL
curl: (92) HTTP/2 stream 0 was not closed cleanly: INTERNAL_ERROR (err 2)
When I use POSTMAN, I get the below error
Error: Stream error in the HTTP/2 framing layer

Now if I call the API directly, I get proper response. I think the error has something to do with http versions. Can anyone help ?
Thank you!

When you say you call the API directly does the request go through Consul?

Can you share the result for the following?

  • curl to Consul to Tyk to your API
  • curl to Consul to your API
  • curl to Tyk to your API

My request flow is like :

                             Consul
                                ^
                                |
  Request --> public nginx --> tyk --> microservice(spring boot)

When I do curl to the microservice directly (docker container) I get the proper response.

I am thinking more of some http version mismatch between Tyk and my SpringBoot microservice.
How do I configure http versions in Tyk ?

I see. But what I am trying to get at is if you remove Consul out of the equation does that do anything?

@tocn - could you check value of "enable_http2": true in the tyk.conf or env var TYK_GW_HTTPSERVEROPTIONS_ENABLEHTTP2=true?

@zaid
I will remove consul and post here if it changes anything.
Here is my consul config in apps directory for reference.

    "service_discovery": {
      "use_discovery_service": true,
      "use_target_list":true,
      "query_endpoint": "http://192.168.34.150:8505/v1/catalog/service/micro-service",
      "use_nested_query": false,
      "endpoint_returns_list":true,
      "data_path":"ServiceAddress",
      "port_data_path":"ServicePort"
    }

@ahmet I do not have that http2 config in my tyk.conf,. Just to show you my current curl responses for Nginx, Tyk and my microservice. All are HTTP/1.1, but I will make that config change in tyk and get back soon. Thanks!

My Tyk reponse for head is this:

curl --head http://192.168.34.150:5555/hello

My public Nginx response for head is this.
